A new module parameter has been added called 'overridesize',
which overrides the size that would be determined by the
ID bytes. 'overridesize' is specified in erase blocks and
as the exponent of a power of two e.g. 5 means a size of
32 erase blocks.

New module parameters have been added to nandsim to
simulate:
bitflips random bit flips
badblocks blocks that are initially marked bad
weakblocks blocks that fail to erase after a
small number of erase cycles
weakpages pages that fail to write after a
small number of successful writes
gravepages pages that fail to read after a
small number of successful reads

When the MTD driver returns write failure, the following deadlock
occurs:
We are in __jffs2_flush_wbuf(), we hold &c->wbuf_sem. Write failure.
jffs2_wbuf_recover()->jffs2_reserve_space_gc()->jffs2_do_reserve_space()
->jffs2_erase_pending_blocks()->jffs2_flash_read()
and it tries to lock &c->wbuf_sem again. Deadlock.

There is a slight bug in nand_default_block_markbad, where the offset is
cast to an integer, prior to being shifted. This means that on large
offsets, it is incorrectly doing a signed shift & losing bits. Fixed
this by doing the cast after the shift (as is done elsewhere in the code).

Add support for AT26Fxxx dataflash devices. These devices have a quite different

Over the years there was a slow trickle of complaints against the readahead
code. Most of them concerned performance, Peter Zijlstra stumbled over it
when working unrelated changes and I believe there was an actual bug report.
Oh, Andrew Morton also complained about duplicating code from mm/readahead.c.
It is just not worth it. On flash media like usb sticks, readahead will
make things go slow - very slow. On spinning disks, readahead may be a
win, but this is definitely not the place to add it.

The TX CCID needs the write_xmit_timer for delaying packet sends. Previously
this timer was only activated on active (connecting) sockets.
This patch initialises the write_xmit_timer in sync with the other timers, i.e.
the timer will be ready on any socket. This is used by applications with a
listening socket which start to stream after receiving an initiation by the
client. The write_xmit_timer is stopped when the application closes, as before.
Was tested to work and to remove the timer bug reported on dccp@vger.
Also moved timer initialisation into timer.c (static).

* Kexec adds some code to arch/ia64/kernel/smp.c which needs ia64_mca_pal_base,
so the kexec patch (actually the kdump patch) declares this
per-cpu variable in include/asm-ia64/kexec.h.
* ia64_mca_pal_base is defined in arch/ia64/kernel/mca.c, so it
seems to me that it would make a lot more sense to declare it in
include/asm-ia64/mca.h.

Jack Steiner noticed that duplicate TLB DTC entries do not cause a
linux panic. See discussion:
http://www.gelato.unsw.edu.au/archives/linux-ia64/0307/6108.html
The current TLB recovery code is recovering from the duplicate itr.d
dropins, masking the underlying problem. This change modifies
the MCA recovery code to look for the TLB check signature of the
duplicate TLB entry and panic in that case.

This moves the device symlink back to sysfs even if
CONFIG_SYSFS_DEPRECATED is enabled as too many userspace programs (well,

I will rework the ability for sysfs to change layouts like this in the
future, but for now, this patch should fix people's network connections.
